I was having this dialogue with myself earlier today as it relates to Yelich and the long term maintenance on his back. Would playing first with the picks and scoops and fast twitch reactions be better to prolong his career or would playing the OF? This all assumes he would be serviceable as a defender at 1B. My thought is whatever will give better rest to that back is where he should go. With a hitter of Yelich's stature, the redundancy aspect is a non issue. You don't sit him vs. LH pitching. Mickey Mantle didn't play an inning of 1B until he was 35. He played there exclusively nearly full time his final 2 seasons. He was far from perfect, making 8 errors in 1967 and 15 in his last year, 1968. But that was in an era when 6 or 7 strikeouts by a staff per game was a lot. I think Yelich would be fine playing there a couple days a week to start when the big strikeout guys, Peralta and Burns are scheduled. Taylor should stay in the outfield. Let him get established as a major league hitter. If it works out that playing first is easier on Yelich's back, all the better.
